Address Shield is an address validation app. It checks the delivery address at checkout and asks your customer to fix anything wrong before it reaches you. Validation runs inside Shopify's checkout, so addresses are never sent to our servers, never stored and never shared. We never rewrite an address, because auto-correction can turn a correct address into a wrong one. Block PO boxes, missing house numbers, missing apartment numbers, special characters, emojis and zip codes you don't ship to.

• Addresses never leave Shopify. Checks run in checkout, nothing is sent to us
• Never rewrites an address. Your customer is asked to fix it, so nothing is lost
• Block missing house numbers, missing apartment numbers and special characters
• Block PO boxes your carriers can't deliver to, and zip codes you don't ship to
• Checkout messages appear in your customer's own language across 11 languages
